  • Measures every 6 hours and transfers the data once a day via WiFi to data server
  • Battery life up to 10 years
  • No limitation of the max. measurable tank volume

Fields of application

  • Proven successful in over 30,000 applications
  • Measures all liquids: heating oil, water, diesel, etc.
  • Suitable for fuel oil tanks, diesel tanks, cellar tanks, underground tanks,
  • reservoirs, storage tanks and ICB drums with a volume of at least 200 litre


EcoFrog is a modern level indicator for the fuel oil tanks and monitor the fill level in the fuel oil tanks and consumption via a web portal or on smartphone. EcoFrog is the alternative for thread floats, dipsticks, fuel meters or other mechanical systems and can also be used where it is impossible to connect to the grid.

Please note the following tank information that is needed.

Please specify the medium in the tank, i.e. water, fuel, etc.

Choose Tanktyp A for rectangular tanks, B for oval or round tanks, C for flat Tanks (W>H)


Height (H) in cm: distance between the tanks floor and bottom tip of the sensor in cm.  If the distance between the sensor and the max. fill line is greater than 15cm  the difference must be entered as offset below. 

Width (W) in cm

Length / depth (Z) in cm

Maximum Volume in Litres: (For use in battery tanks please enter the combined volume of all tanks.)

The level of the intake at the bottom of the tank.  Default setting is 8cm.

Offset: In order to get more accurate measurements place the sensor 15cm above the maximum fill line. If this distance is more than 15cm and there is an empty area please spcifiy it here in X cm (total distance in cm between sensor and surface - 15cm = X)
